# genealogytree with multiple marriages on both sides

Suppose A had child X with B and child Y with C. I know that union works to get this done:

\begin{tikzpicture}
\genealogytree[template=formal graph,
]
{child{
g[id=a, tikz={xshift=9mm,yshift=0mm}]{A}
union{
p[id=b, tikz={xshift=-9mm,yshift=0mm}]{B}
c[id=x]{X}
}
union{
p[id=c]{C}
c[id=y]{Y}
}
}
}
\end{tikzpicture}


(the shifts are to prevent intersections)

But what if B also had child Z with some D? what I'm doing right now is add parent:

\documentclass[a4paper,landscape]{article}
\usepackage[top=4.5cm, bottom=4.5cm, left=1cm, right=1cm]{geometry}
\usepackage[all]{genealogytree}
\begin{document}
\begin{tikzpicture}
\genealogytree[template=formal graph,
add parent = b to fam_B
]
{child[id=fam_A]{
g[id=a, tikz={xshift=9mm,yshift=0mm}]{A}
union{
p[id=b, tikz={xshift=-9mm,yshift=0mm}]{B}
c[id=x]{X}
}
union{
p[id=c]{C}
c[id=y]{Y}
}
}
child[id=fam_B, edges up = 1 of 4]{
g[id=d, tikz={xshift=-15mm,yshift=0mm}] {D}
c[id=z, tikz={xshift=-9mm,yshift=0mm}] {Z}}
}

\end{tikzpicture}
\end{document}


This produces

which is great except the edges only come out of B at one spot (compare with the two edges coming out of A). I can't seem to find a way to adjust the edge start points, just the central nodes.

Is there a way to do this nicely? I'm hoping for something generalizable to more than two marriages on each side (with copious amounts of shifts).

One way is to color each node and highlight wife2 and the progeny with green -- and color wife3 and progeny in blue -- tracing is easier -- off course the edges can also be segregated based on color

\documentclass[a4paper,landscape]{article}
\usepackage[top=4.5cm, bottom=4.5cm, left=1cm, right=1cm]{geometry}
\usepackage[all]{genealogytree}
\begin{document}
\begin{tikzpicture}
\genealogytree[template=formal graph,
% add parent = b to fam_B
options for node={wife2, childw2}{box={colback=green!20!white}},
options for node={wife3, childw3}{box={colback=blue!20!white}},
]{

child{
g[male]{Husband}
p[female]{Wife1}
c[female]{childw1}
% c[male]{a_4}
% c[female]{a_5}
union[id=fam_2]{
p[id=wife2,female]{Wife2}
c[id=childw2,female]{childw2}
% c[id=nd3,male]{d_3}
% c[id=nd4,male]{d_4}
}

union[id=fam_3]{
p[id=wife3,female]{Wife3}
c[id=childw3,female]{childw3}
% c[id=nd3,male]{d_3}
% c[id=nd4,male]{d_4}
}
}
}
\end{tikzpicture}
\end{document}


With custom edges

\documentclass[a4paper,landscape]{article}
\usepackage[top=4.5cm, bottom=4.5cm, left=1cm, right=1cm]{geometry}
\usepackage[all]{genealogytree}
\begin{document}
\begin{tikzpicture}
\genealogytree[template=formal graph,
% add parent = b to fam_B
options for node={wife2, childw2}{box={colback=green!20!white}},
options for node={wife3, childw3}{box={colback=blue!20!white}},
]{

child{
g[male]{Husband}
p[female]{Wife1}
c[female]{childw1}
union[id=fam_2, family={edges={foreground={green!30}}}]{
p[id=wife2,female, ]{Wife2}
c[id=childw2,female]{childw2}
}

union[id=fam_3, family={edges={foreground={blue!30,}}}]{
p[id=wife3,female,]{Wife3}
c[id=childw3,female]{childw3}
}
}
}
\end{tikzpicture}
\end{document}


• Thank you. This does help distinguish children from different marriages, but I am hoping to adjust the edges so that previous marriages of both the husband and the wife will have separate edges. Aug 28 at 21:05
